Euler Angles are a set of three angles that describe the orientation of a rigid body in three-dimensional space. They are commonly used in fields like robotics, aerospace, and computer graphics to represent rotations. The angles are typically denoted as φ (phi), θ (theta), and ψ (psi), which correspond to rotations around the three principal axes. These angles can be defined in various sequences, leading to different conventions, such as Z-Y-X or X-Y-Z. Each sequence affects the final orientation of the object, making it essential to choose the appropriate convention for specific applications.
